Abstract
In recent years, according to very rapid increase of various kinds of information and communication equipment like personal computers and portable radio transmitters, not only a problem of the technical characteristics of equipment and propagation but also a problem of the influence to the environment including human body has become gradually important. In this study, some evaluation and/or measurement methods for compound effect based on the inter-subjective relationships between sound (with other environmental factors) and psychological or physiological factors have been proposed, especially through some examples of the physical factors (sound, lights, magnetic field and temperature) and the psychological or physiological factors (noise evaluation values, mean blood pressure and pulsation) surrounding an indoor electrification environment. Finally, with an application to actually measured data, a part of the effectiveness of the proposed method has been also experimentally confirmed.
